Microsoft has just announced a chip that it claims will "redefine" how quantum computing works. But experts say there's a long way for that vision to become a reality.

Majorana 1 relies on ‘topological superconductivity,’ a never-before-seen theoretical form of matter.

Microsoft says it has developed a breakthrough quantum processor based on a new state of matter, giving it a clear path to achieve quantum computing’s long-term promise of solving some of the world’s most difficult problems.
